The AM64 monoclonal antibody specifically binds to CD130 which is also known as gp130 (Membrane glycoprotein 130), IL6ST (Interleukin-6 signal transducer), and IL6RB/IL-6Rβ (Interleukin-6 Receptor beta). CD130 is a 130 kDa type 1 membrane glycoprotein that belongs to the hemopoietic cytokine receptor superfamily. CD130 serves as a common signaling receptor for several cytokine receptor complexes including those that mediate the biological effects of IL-6, IL-11, IL-27, Cardiotrophin-1 (CT-1), Ciliary neurotrophic factor (CNTF), Leukemia inhibitory factor (LIF), and Oncostatin M (OSM). CD130 is widely expressed on a variety of cell types including T cells, activated B cells, monocytes, plasma cells, and endothelia. The AM64 antibody can be used in flow cytometry, immunoprecipitation, western blot, and immunohistochemistry on frozen sections.
The antibody was conjugated to BD Horizon BUV661 which is part of the BD Horizon Brilliant™ Ultraviolet family of dyes. This dye is a tandem fluorochrome of BD Horizon BUV395 with an Ex Max of 348-nm and an acceptor dye with an Em Max at 661-nm. BD Horizon Brilliant BUV661 can be excited by the ultraviolet laser (355 nm) and detected with a 670/25 filter and a 630 nm LP. Due to cross laser excitation of this dye, there may be significant spillover into channels detecting APC-like emissions (eg, 670/25-nm filter).
